Abstract

The potential geographic distribution and favorable climatic conditions of Machilus thunbergii under current and future predicted climates in China are predicted based on MaxEnt model and ArcGIS software. The results show that the AUC values in different time periods and emission seniors are more than 0.9, which indicates the prediction is excellent. Precipitation of the coldest quarter, precipitation of the driest month, annual precipitation, mean diurnal range, and temperature annual range are the most important environmental factors affecting the distribution of Machilus thunbergii. At present, the suitable areas of Machilus thunbergii are mainly concentrated in the eastern subtropics of China, with a total area of 118.47 × 104 km2. The medium-suitability area and the high-suitability area are concentrated in Wuyi Mountains, Luoxiao Mountains, Xuefeng Mountains, Nanling and east of Taiwan Mountains. With the change of climate, the suitable area increases, and the medium-suitability area and high-suitability area migrate and expand to the east, and the low-suitability area expands slightly to the west and north. So, the simulated distribution of Machilus thunbergii should be one of priorities, when instigating in-situ conservation. The research results can provide a theoretical reference for the popularization and planting of Machilus thunbergii.
气候变化模式下中国黄芪潜在分布的模拟
基于MaxEnt模型和ArcGIS软件,预测了在当前和未来预测气候条件下,东北东北东北东北地区东北东北东北的潜在地理分布和有利气候条件。结果表明,不同时间段和排放老年人的AUC值均大于0.9,表明预测效果良好。最冷季度的降水量、最干燥月份的降水量和年降水量、平均日变化范围和温度年变化范围是影响浙梅分布的最重要的环境因素。目前,川东北的适宜区主要集中在中国东部亚热带,总面积为118.47×104km2。中等适宜区和高适宜区集中在武夷山、罗晓山、雪峰山、南岭和台湾山东部。随着气候变化,适宜区增加,中适宜区和高适宜区向东迁移扩展,低适宜区向西、向北略有扩展。因此,在倡导原位保护时,应优先考虑模拟川柳的分布。研究结果可为浙梅的推广种植提供理论参考。
